The AST Suspension Lowering Springs for the 2002+ Nissan Primastar are high-performance coil springs designed to reduce ride height by 30mm. Crafted from premium high tensile chromium-silicone wire, these springs are engineered for durability and consistent performance. Each spring undergoes a meticulous manufacturing process, including cold winding, heat treatment to enhance hardness, and shot peening to improve fatigue life. The phosphate coating and powder coating finish provide corrosion resistance and longevity, ensuring the springs maintain their integrity over the vehicle's lifespan. These springs feature progressive rates on most applications, offering a balance of improved handling and ride comfort while maintaining factory-like ride quality.
Designed specifically for the 2002 and newer Nissan Primastar models, including F7, X83, FL, JL, F4, and J4 chassis codes, these lowering springs are a direct replacement for the factory components. They are suitable for street use, providing a lowered stance that enhances vehicle appearance and handling without compromising daily drivability. Installation is straightforward as bolt-on components, compatible with existing suspension setups. The kit includes the set of springs, with no additional components required. These springs are ideal for enthusiasts seeking improved handling and aesthetics on their Primastar, whether for daily driving or light performance upgrades.
